Bethany bought a box of markers. She gave 6 to her friend. If Bethany now has 52 markers, how many markers were in the box she bought?
Answer:
58 markers
Step-by-step explanation:
52 + 6 = 58
Answer:
58 markers
Step-by-step explanation:
x-6=52 Set up the problem. "x" represents the number of markers.
+6 +6 Add 6 to both sides to isolate x
x =58

H+ ions increase in concentration at lower pH values. Calculate how many more H+ ions there are in a solution at a pH = 2 than in a solution at a pH = 6. Find the concentration of H+ ions at a pH = 2 and at a pH = 6 in Table B. Then divide the concentration of H+ ions at a
pH = 2 by the of H+ ions at a pH = 6. Record your answer in Table C.
What is the concentration of H+ ions at a pH = 2?
mol/L
What is the concentration of H+ ions at a pH = 6?
mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
Answer:
What is the concentration of H+ ions at a pH = 2?
⇒ 0.01 mol/L
What is the concentration of H+ ions at a pH = 6?
⇒ 0.000001 mol/L
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?
⇒ 10,000
Step-by-step explanation:
Answer:
What is the concentration of H+ ions at a pH = 2?
0.01
What is the concentration of H+ ions at a pH = 6?
0.000001
How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?

Ahmed owns a land of breadth (x+7) units &having an area of 2+ 14x + 49 sq. Units. (i)Find its length.
Answer:
l = (x+7) units
Step-by-step explanation:
Given that,
Breadth of the rectangle, b = (x+7) units
Area of the rectangle, [tex]A=x^2+14x+49[/tex]
The area of a rectangle is given by :
[tex]A=lb\\\\l=\dfrac{A}{b}\\\\l=\dfrac{(x^2+14x+49)}{(x+7)}\\\\l=\dfrac{(x+7)^2}{(x+7)}\\\\l=(x+7)\ \text{units}[/tex]
So, the length of the land is (x+7) units.

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?
Answer:
zero
Step-by-step explanation:
The computation of the remainder when the number would be divided by 35
Let the number be x
So if x is divided by 5 gives the remainder 0
x = 0
And, if x is divided by 7 gives the remainder 0
x = 0
So if x is divided by 35 so the remainder is also zero

The coordinates of the vertices of a triangle are A( 2,3) , B ( 9,1) , C ( 12,14) Suppose each coordinate is multiplied by 3. What is the perimeter of this triangle?
9514 1404 393
Answer:
about 106.5 units
Step-by-step explanation:
The length of each side is found using the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of side AB is ...
d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28
The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...
AB +BC +CA = 7.28 +13.34 +14.87 = 35.49
__
Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...
3(35.49) ≈ 106.5 . . . . units

Erin buys a bag of peanuts that weighs 3/4 of a pound later that week the bag is 2/3 full how much dose the bag of panuts wiegh now
Answer:
1 ÷ 2 pounds
Step-by-step explanation:
The computation is shown below:
As we know that
1 pound = 0.454 Kg
Peanut starting weight = 3 ÷ 4 of a pound.
In the case when the bag is 2/3 full, so the weight is
= 2 ÷ 3 × 3 ÷ 4
= 1 ÷ 2 pounds

Answer:
Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
Answer:
yes.
Step-by-step explanation:
slope intercept form is y=mx+b
b is the y intercept, m is the slope, and x is x.
for
1. it would be
y= -4/5x -9
2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)
it would look like:
(5- -3) / (3-0) = (8/3)
Then plug in one of the sets of numbers for x and y, to get y intercept.
5=8/3(3)+b
b=-3
So.. slope intercept would be y=8/3x -3

The circumference of a circle is m. What is the area , in square meters ? Express your answer in terms of pi
Answer:
area = m²/2π
Step-by-step explanation:
∵ circumference of circle = 2πr = m
∴ r = m/2π
∵ area of circle = πr²
∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π
